REAR SlGHT FOR FIRE-ARMS.

SPECIFICATION forming part of Letters Patent No. 382,130, dated May 1, 1888.

Application filed January 14, 1888. Serial No. 260,744.

To aZZ whom it may concern:

Be it known that I, DANIEL V. BEAN, a citizen of the United States, residing at Plover, in the county of Portage and State of Wiscon* sin, have invented a certain new and useful Improvement in Rear Sights for Fire-Arms, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming apart of this specification, in which- Figure l representsaside view of a rear sight for fire-arms with my improvement attached. Fig. 2 is a face view of the same.

My invention relates to rear sights for firearms; and it consists in the improved sight hereinafter fully described and claimed.

To enable others skilled in the art to make and use my invention, I will now describe the exact manner in which I have carried it out.

In the said drawings, A represents a rearsight plate faced solidly with any white material and provided on its upper line with the curved indentation a, at the bottom of which, and below its central point, I insert a black or dark spot, I), over which accurate aim can be quickly taken as well in cloudy as in clear weather.

Before the sight-plate is covered with white material it is cut away in circular form, leav- (No model.)

ing enough of the material at the bot-tom for the wedge c of the sight to bear upon. The front is then faced with any white materialsuch as ivory-said material being thin enough so that the light will show through it. This makes the black spot more conspicuous and gives more light, and the more light that can be centered around the black spot the better or more effective the sight will be and the clearer the black spot or line can be seen.

I am aware that sights for firearms have been made with two contrasting colors, one of which formed a vertical line between two lines of the other color, and also in which a central line of white or light-colored substance was formed with a dark line on either side; but such I do not claim as my invention.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-

A rear sight of white material having a u curved or depressed upper surface and an underlying dark spot at the central point of said depression, said spot being in contradistinc tion to a vertical line.
